Description
N 8 aluminium crimp cap with open top is a silver-finish sealing component for chromatography sample vials, fitted with a PTFE red/silicone white/PTFE red laminated septum. The septum is specified at 50° Shore A hardness and 1,0 mm thickness, supporting reliable needle penetration and resealing during routine GC and HPLC workflows. The aluminium shell provides a stable crimp closure on matching N 8 neck finishes, helping maintain sample integrity from preparation through injection. Supplied in packs of 100 pieces, this configuration suits high-throughput laboratories that standardise on red PTFE-faced silicone septa for broad solvent compatibility. The open-centre design allows clear access for autosampler or manual syringes while the multi-layer septum construction separates the sample contact face from the silicone core. These crimp caps from manufacturer Macherey-Nagel are intended as consumable vial closures in analytical chemistry, quality control and method development environments where consistent septum geometry and hardness are required for reproducible sealing performance.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about CC N8-H si, PTFEr/Sil w/PTFEr, 50°, 1.0
What is this article?
CC N8-H si, PTFEr/Sil w/PTFEr, 50°, 1.0 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
